Question

Quizplus · Accepted Answer

A strong positive correlation indicates that there is a numerical relationship between the two variables, meaning that as one variable (hours spent on campus) increases, the other variable (grades) also tends to increase. It does not necessarily indicate causation, as there could be other factors at play. Therefore, choices A and D are not necessarily true. The correlation coefficient cannot be concluded from the information given, so choice B is not a valid conclusion.
